On the assumption that theistic religious commitment takes place in the face of evidential ambiguity, the question arises under what conditions it is permissible to make a doxastic venture beyond one’s evidence in favour of a religious proposition. In this paper I explore the implications for orthodox theistic commitment of adopting, in answer to that question, a modest, moral coherentist, fideism. This extended Jamesian fideism crucially requires positive ethical evaluation of both the motivation and content of religious doxastic ventures. I (...) suggest that, even though the existence of horrendous evil does not resolve evidential ambiguity in favour of atheism, there are reasonable value commitments that would preclude those who hold them from satisfying extended Jamesian fideist conditions for committing themselves to classical theism. I then begin a discussion of a possible revisionary theistic alternative (in the Christian tradition) which – one might hope – may meet those conditions. An earlier, shorter, version of this paper was delivered as a keynote address at the APA Pacific 2007 Mini-Conference on Models of God. (shrink)

Perfect being theism is the view that the perfect being exists and the property being-perfect is the property being-God. According to the strong analysis of perfection, a being is perfect just in case it exemplifies all perfections. On the other hand, the weak analysis of perfection claims that a being is perfect just in case it exemplifies the best possible combination of compatible perfections. Strong perfect being theism accepts the former analysis while weak perfect being theism accepts the latter. In (...) this paper, I argue that there are good reasons to reject both versions of perfect being theism. On the one hand, strong perfect being theism is false if there are incompatible perfections; I argue that there are. On the other hand, if either no comparison can be made between sets of perfections, or they are equally good, then there is no best possible set of perfections. I argue for the antecedent of this conditional statement, concluding that weak perfect being theism is false. In the absence of other analyses of perfection, I conclude that we have reason to reject perfect being theism. (shrink)

In this article, I discuss Anselmian theism, which is arguably the most widely accepted form of monotheism. First, I introduce the core theses of Anselmian theism and consider its historical and developmental origins. I contend that, despite its name, Anselmian theism might well be older than Anselm. I also claim, supporting my argument by reference to research in the cognitive science of religion, that, contrary to what many think, Anselmian theism might be a natural result of human cognitive development rather (...) than a mere philosophical artefact. Second, in the course of explaining the merits of Anselmian theism, I argue that this doctrine seems to benefit from at least three virtues. Third, I discuss existing arguments against Anselmian theism and maintain that most of them can be classified into three types. Finally, I suggest a novel strategy on the basis of which it is possible to defend Anselmian theism from these arguments. (shrink)

Latest version of my SEP entry on ontological arguments, which first appeared in 1996. General discussion of ontological arguments. Includes a brief historical overview, a taxonomy of different kinds of ontological arguments, a brief survey of objections to the different kinds of ontological arguments identified in the taxonomy, and more extended discussions of Anselm's ontological argument (Proslogion 2), Godel's ontological argument, and Plantinga's ontological argument.

The Anselmian claim that God is that than which a greater cannot be thought in virtue of being ‘whatever it is better to be than not to be’ may be accused of incoherence or even unintelligibility. By proposing a non-relative but apparently meaningful analysis thereof, I attempt to defend it against such criticism. In particular, I argue that ‘whatever it is better to be than not to be’ can be plausibly interpreted so as to imply very many attributes traditionally predicated (...) of that than which a greater cannot be thought. Central to this line of reasoning is the assumption that whatever is an actual moral being is greater, simpliciter, than whatever is not an actual moral being. (shrink)

This paper is a defense of the view that existence is a perfection. Anselm’s First Ontological Argument is referred to throughout. Two major objections are advanced: the ‘perfect island’ objection and the ‘perfect devil’ objection. A rebuttal of both, based on Anselm’s reply to Gaunilo, is tendered, but itself faces a major objection. Two lines of defense against this objection are possible. The first is sympathetically explained but it is argued that it ultimately fails. The second, which focuses on the (...) idea of a perfection and a perfect being, is elaborated and defended against a seemingly powerful objection. It is concluded that there is a reasonable interpretation of the claim that existence is a perfection. (shrink)

The notion of omnipotence has proved to be quite recalcitrant to analysis. Still, during the last three decades or so, there has resurfaced a clever argument to the effect that, whatever omnipotence is, it cannot be exemplified in God: an allegedly impeccable and all-perfect being. Scrutinizing this argument, however, I find it less than convincing. Moreover, and more importantly, I venture a positive account of my own: a non-technical and distinctively metaphysical definition of omnipotence which, if true, sidesteps quite a (...) number of well-known pitfalls. Also, by way of introduction, I review some earlier attempts. (shrink)
